Types of Fish Food: Flakes, Pellets, Freeze-Dried & Live
Fish Flakes
Fish flakes are light, fluffy bits of fish food that float on the surface of the water. They come in a variety of sizes for different fish. Flakes are a popular, inexpensive option for many hobbyists because most fish find them appetizing and they’re easy to feed. However, flakes tend to make a mess, break apart quickly, and lack some nutrients. They should only make up part of a balanced diet for your fish.
Fish Pellets
Pellets are a step up from flakes and provide more nutrition in each bite. They’re made from compressed fish meal, grains, and supplements. Pellets come in sinking and floating varieties and different sizes for your fish. They’re a good staple food but should still be supplemented with other options for the healthiest diet.
Freeze-Dried Foods
Freeze-dried fish foods contain natural, unprocessed ingredients in a concentrated form. They retain more nutrients than flakes or pellets. Many hobbyists use freeze-dried foods as a supplement to provide extra nutrition. However, they can be expensive and may need to be rehydrated before feeding to some fish.
Live Foods
For many fish, live foods provide enrichment and natural stimulation. Options like brine shrimp, bloodworms, daphnia, and tubifex worms are excellent sources of protein and other nutrients. Live foods are a great treat, but they should not make up the entire diet, as they lack certain nutrients. They also require extra effort to culture and feed.
A balanced diet with a variety of high-quality fish foods will keep your fish energetic, active, and brightly colored. Offer several types of food each day, in amounts your fish can eat within about 2 minutes at each feeding. Remove any uneaten food from the tank within a few minutes to avoid pollution. With the right mix, your fish will be healthy and happy for years to come!
Choosing the Right Fish Food Based on Fish Species
For Carnivorous Fish
If you have predatory fish like cichlids, catfish or loaches, you’ll want to choose a high-protein fish food made of meaty ingredients. Foods with fish meal, krill, shrimp or bloodworms as the first few ingredients are excellent for carnivorous fish. The more protein sources, the better. These fish need a diet high in protein (around 45-50%) to fuel their active, predatory lifestyle.
For Herbivorous Fish
For fish that graze on algae and plants, such as goldfish, koi and some tropical fish, choose an algae-based or spirulina-enhanced flake food. These provide the vegetable matter and plant proteins herbivorous fish need. As with carnivorous fish, aim for at least 45-50% protein but with multiple plant-based protein sources listed high on the ingredients. Algae, spirulina, and wheat germ are excellent options.
For Omnivorous Community Fish
If you have a variety of fish in your tank with different dietary needs, an all-purpose flake food or pellet is your best choice. Look for ingredients like fish meal, krill meal, and algae or spirulina. These provide a good mix of proteins from both animal and plant sources to satisfy omnivorous fish. The protein content should still be 45% or higher to meet the needs of both carnivores and herbivores in the tank.
Amount and Frequency
For most community fish, 2-3 small pinches of food 2-3 times per day is a good starting point. Watch your fish during feeding to see if they finish all the food in about 2 minutes. If so, you can increase the amount slightly with each feeding. If there are leftovers that go uneaten after a few minutes, cut back the amount at the next feeding. It’s best to slightly underfeed than overfeed your fish. Remove any uneaten food from the tank within a few minutes of feeding to avoid pollution.
With the right diet for your fish based on their species and needs, your fish will be active, healthy and happy. And a thriving, energetic fish community is a sight that never gets old!
Reading the Fish Food Label: What to Look For
When choosing a fish food, it’s important to examine the ingredients list and nutritional information to ensure your fish get the proper diet. Look for a formula specifically for your breed of fish to meet their unique needs. For most aquarium fish, you want a balanced diet with protein as the first or second ingredient.
High-Quality Protein Sources
Look for whole fish meal, shrimp meal, or spirulina as the primary protein source. Fish meal and shrimp meal provide omega-3 fatty acids and essential amino acids. Spirulina is a nutritious algae high in protein, vitamins, and minerals. Avoid unspecified “fish meal” or “meat meal,” as these can be made from undesirable byproducts.
Limited Fillers
Fillers like wheat, corn, and soy provide little nutrition. These should not be in the first few ingredients. Some filler is okay for binding pellets together, but too much will reduce the amount of nutritious ingredients.
Vitamins and Minerals
Look for added vitamins like A, B, C, D, and E as well as minerals such as calcium, phosphorus, and magnesium. These help support healthy growth, disease resistance, and longevity.
Preservatives and Artificial Colors
Avoid fish food with artificial preservatives like BHA, BHT or ethoxyquin which some studies have found harmful. Artificial colors are unnecessary and may be harmful.
Pellet Size
Choose a pellet size suitable for your fish. Pellets that are too large for small fish to eat will end up wasting food and polluting your tank. Pellets that are too small for large fish won’t provide enough nutrition.
By understanding fish nutrition and learning how to read labels, you can choose a quality fish food that will keep your fish active, vibrant, and healthy for years to come. Focus on natural, whole ingredients and the right formula for your breed of fish. Your fish will reward you for it!
Feeding Your Fish the Proper Amount
To keep your fish healthy and happy, it’s important to feed them the right amount of food. Overfeeding can lead to obesity, disease, and a dirty aquarium. Underfeeding will cause malnutrition and stunted growth. As a general rule of thumb, only feed your fish as much food as they can eat in about 2 minutes, 2-3 times per day.
For most community fish like tetras, guppies, and cichlids, start with a small pinch of food, about as much as can fit on the tip of your finger. Gently sprinkle it over the top of the aquarium and watch your fish eat. If they finish it quickly and are still actively searching for more food after 2 minutes, you can add a little bit more at the next feeding. It’s best to underestimate how much to feed rather than overfeed. You can always add more food, but you can’t take it back out!
As your fish get used to a feeding schedule, they will start to anticipate feeding times. Be careful not to feed them every time they beg for food, or you’ll end up overfeeding. Stick to a regular schedule and amount to keep your fish at a healthy weight. Only increase the amount of food if you start to notice your fish looking thin or if there are no leftovers after 2 minutes of feeding.
Some fish like goldfish, koi, and large cichlids may require a bit more food to maintain a healthy weight due to their size. But in general, it’s best to be conservative and increase slowly. Remember, you can always feed your fish a little more, but you can never take the food back! By monitoring your fish during feedings and making small adjustments as needed, you’ll get a feel for the proper amount of food to keep your fish looking and acting their best.
Storing Fish Food Properly to Maintain Freshness
Keep it Cool and Dry
The ideal spot to store your fish food is in a cupboard away from heat and moisture. High temperatures and humidity can cause fish food to spoil more quickly by promoting the growth of molds and bacteria. A pantry, cabinet or closet away from appliances like the stove, oven or water heater is perfect.
Use an Airtight Container
Once you open your fish food, transfer it to an airtight container like a plastic or glass jar with a sealing lid. This will keep the air out and prevent the food from getting stale. Plastic bags are not optimal for long-term storage, as they don’t keep air out very well. Label and date the container, so you know when you first opened the food. Most dry and flake fish foods will stay fresh for about 6-12 months after opening when stored properly.
Don't Buy in Bulk

Only buy as much fish food as you can use within a few months. Large bags may seem more economical, but the food can lose nutrition and taste over time. It’s best to buy a smaller container and replenish more frequently to ensure your fish are getting the freshest food possible.
Check for Freshness
There are a few ways to check if your fish food is still fresh. First, examine the color and texture. Food that is past its prime may be dull in color or have an oily, clumpy texture. Next, do a smell test. Fresh food should have an earthy, nutty smell. Discard anything with a sour, musty or unpleasant odor. Finally, do a taste test by sampling a few pellets or flakes. They should taste bland but not bitter or spoiled. If anything seems off, throw out the old food and get your fish a new supply.
By following these tips for proper fish food storage, you can maintain optimum freshness and nutrition. Your fish will appreciate the difference, remaining vibrant and active when fed a diet of high-quality, fresh food.
